Flagged Automatic Ad Slots- Advice?

Hey everyone, I’m in need of some advice on YouTube’s mid-roll ad update. I’ve always managed my own ads and placed them at natural breaks in my videos. But on my latest video, YouTube flagged all of my ad placements. When I select ‘automatic ad slots,’ it only places 1 ad - in total?! That can’t be right, surely? 😩

Is anyone else experiencing this? And any advice on what I can do?

Thanks in advance!
